Which of the new apple varieties has a chance to take a place in our assortment?

Keywords: Asfari, Rockit®/PremA96, Joly Red, Maribelle/Lola®, Sweet Surprise®/B3F45, Kizuri, Natyra®/SQ159

Variety testing of apples
From each variety we plant 10 trees on M9, of which 6 trees are planted in a parcel with a normal spraying scheme (IPM). 4 trees are planted in a parcel with limited use of fungicides. We only spray against scab when there is a high risk on scab (2 to 4x pro year). In this parcel we don’t spray against powdery mildew, storage diseases and Nectria canker. For the scab resistant varieties we also plant 5 trees in a parcel where we only use copper or sulphur to control scab and powdery mildew. As reference we plant always Jonagored and Golden Reinders. For the observations we use the EUFRIN Descriptor list. Annually a report is sent to the breeders/licensors.

In the first screening no chemical thinning (only by hand) and no treatments with gibberellins against russeting are used. Furthermore only a few branches are bent, so we can judge the natural tree shape of the new apple variety. At dryness it is possible to irrigate and there is protection with overhead sprinklers against spring night frost. This way we are certain that the trees rapidly come in production and that we have a (good) production every year. After 3 to 4 production years a first selection is made. Varieties that are not good enough are grubbed.

From the best varieties in the first screening 40 to 120 trees are planted in a second screening. The eventual goal is to make a technical guide for the fruit growers.

Conclusion
Joly Red, Maribelle/Lola® and Rockit®/PremA96 are already planted to a limited extent and are likely to increase in importance in the coming years. Kizuri and Natyra®/SQ159 certainly have the potential to claim their place, much will depend on who commercialize these varie-ties. For Asfari and definitely Sweet Surprise®/B3F45 it will be much more difficult.
